Does the dictionary meaning of a first name help genealogy?

Only as colour. Families chose names for saints, grandparents, godparents and fashion, not because Margaret means pearl. The useful question is why this household used this name in this parish and decade, which you answer from the acts, not from a baby-name site.

What is a naming pattern and can I rely on it?

Many families honoured grandparents in a loose order: first son for the father's father, first daughter for the mother's mother. It is common and useful as a hint. It is not a law, and breaking the pattern after a quarrel or a move is just as informative.

Why do siblings share a first name in older families?

A second child often received a name after an infant death. The household was keeping the name in use, not repeating it for sentiment alone. Always check burial registers before you merge two children who look like a duplicate in an index.

How should I search nicknames and translations?

Search every form the clerks used: Bill and Wm for William, Jean and Johanna, Seán and John, Hans and Johannes. Record which spelling appears on which document instead of picking a favourite and correcting the rest. Indexes usually store only one version.

Why does a French or Spanish act list so many given names?

Multiple given names are normal. The name used at home may be the second or third on the register, and one of them may honour the saint of the baptism day rather than a grandparent. Copy the full string in the original order before you decide which name to search.

Can a fashionable first name prove nationality?

No. Edward in 1901 England or José in Texas tells you about fashion and language, not about a medieval ethnicity or a precise birthplace. Nationality and origin come from places on records, not from the popularity of a given name.

How do godparents explain an unexpected first name?

Sponsors often lent their own names to the child. If a baptism looks out of family, index the godparents and follow them into later marriages and deaths. They are usually relatives or close neighbours and they reappear as witnesses.

Should I trust a baby-name website for historical research?

Not as a source. Those sites mix etymology, mythology and modern popularity charts. Use them to understand a language family, then go back to the baptism or civil act. A first name becomes evidence only when you can attach it to a documented family decision.
